One-year outcome of an interactive internet-based physical activity intervention among university students.

Objective: The purpose of the present study was to evaluate whether improvement in physical activity of students following a 4-month intervention of a university course was maintained 8 months later.

Methods: Data on 77 students who responded to our scheduled inquiries completely through 1 year were analyzed. Participants of the intervention group (n=49) using the internet-based physical activity program exhibited significant increases in energy expenditures measured by IPAQ compared with the no-treatment control group (n=28) through 1 year.
